Application led February 2, 1916. Serial No. 75,761.

To all whom t may concern.'

Be. it known that I, ALVA L. BROWN, a citizen of the United States,residing at Mc- Kinley, in the county of Coos, State of Oregon, haveinvented certain new and useful Improvements in Milk- Can Closures; andI do hereby declare the following to be a full, clear, and exactdescription of the in.

. vention, such as will enable others skilled in the art to which itappertains to make and use the same.

rfhe present invention is directed to impro vements in millr canclosures, and has for its object to so construct a device of thischaracter that when in place the danger of the closure becomingaccidentally disengaged is eliminated.

A further object of the invention is to provide a closure of this typeso constructed that should the can be tampered with in an attempt toopen the same during transportation the card bearing the consignees namewill be mutilated.

A further object of the invention is to provide a device of thischaracter so constructed that when the closure is in place the can willbe firmly sealed and practically air tight.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawings, in which:

Figure 1 is a top pla-n view of a can equipped with the closure. Fig. 2is a sectional view on line 2 2 of F ig. l. Fig. 3 is a plan view of theclosure, the locking plate removed. Fig. a is a side elevation. Fig. 5

is a sectional view on line 5 5 of Fig. 1. Fig. 6 is a sectional view online 6--6 of Fig. 1.

Referring to the drawing the numeral 1 designates the can having theusual neck 2 4 which terminates in an outwardly flared rim 3, said rimhaving its upper edge provided with an annular flange 1, said flangebeing provided with paired notches 5, the purpose of which will appearlater.

5 The cover 6 is provided with an annular flange 7 which is adapted toengage the flange 4 of the neck, and is provided with diametricallydisposed lugs 8 which are adapted to engage in t-hel depressions 9formed in the flange 4, and when engaged said strip being furtherprovided with an opening 13 and in which is engaged a bolt 11. Pivotallyconnected to the strip 11 by the bolt 1i is a locking plate 15, saidplate having arcuate heads 16 which are provided with inwardly bent ears17, said ears being adapted to pass through the notches 5 and uponpartially rotating the plate 15, the ears will engage under the flange lof the neck, thus holding the cover 'firmly in place.

lThe locking plate 15 has formed therein a chamber 18, which terminateson one of the heads 1b in an angular chamber 19. F iXed in any suitablemanner in the chamber 18 is a rod 20, said rod having an angular arm 21,which is engaged in the chamber 19 and has its end sharpened, as at 22.The arm 21 is resilient so that it will yieldably engage the surface ofone of the heads 11 of the strip 10.

One of the heads 16 is provided with a sight opening 23 which is closedby the glass 21, whereby the card 25 having printed thereon theconsignees name can be readily observed, said card being pasted on theadjacent head 11 of the plate 10 so as to be in the path of movement ofthe sharpened end 22 of the arm 21 when the locking plate 15 is rotated.Thus it will be seen that should a person attempt to open the can thesharpened end 22 of the arm 21 will mutilate the card.

The cover is placed in the neck after which the ears 17 of the heads 16are passed through the notches 5, after which the locking plate isturned clockwise so that the sharpened end 22 of the arm 21 willrideover the card 25, and at which time the lock* ing plate and strip are indirect alinement. Now, to open the can it is necessary to rotate thelocking plate 15 so as to bring the ears 17 in registry with the notches5. Thus it will be seen that when the locking plate is turnedanti-clockwise that the sharpened end 22 of the arm 21 will remove ormutilate the card 25, thus indicating that the can has been opened intransit.

What is claimed is:`-

l. The combination with a can, of a cover therefor, a strip supportedtransversely kor the cover, a locking plate pivotally connect'- ed tothe strip and having a resilient arm associated therewith adapted t0slidably engage the strip When the locking plate is rotated, as yand orthe purpose set forth.

2. The combination With a can 'having a neck, of a flange carried by theneck and having notches formed therein, a cover removably mounted in theneck and having a strip xed'transversely thereof, a lockingplatepivotally connected to the strip and having headsv formed upon itsends, earscarn red bythe heads for passage through said notches, an armassociated With therloeking yplate y and yieldably and slidably engagedwith the strip, aV card associated with vthe strip and adapted to beengaged by said arm when moved in one direction to mutilate or removethe card, as andy for the purpose set forth., y n
